From d8058480b35dbc3d1e6085b3f13b80af27def09e Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 2 Oct 2007 22:27:29 +0800 Subject: [PATCH] [CRYPTO] api: Explain the comparison on larval cra_name This patch adds a comment to explain why we compare the cra_driver_name of the algorithm being registered against the cra_name of a larval as opposed to the cra_driver_name of the larval. In fact larvals have only one name, cra_name which is the name that was requested by the user. The test here is simply trying to find out whether the algorithm being registered can or can not satisfy the larval.
